ACTINIUM – Targeting Interests in the Ukraine
FortiGuard Labs is aware of various campaigns targeting Ukraine by threat actors known as ACTINIUM/Gamaredon/DEV-0157. ACTINIUM’s modus operandi targets various verticals to conduct cyber espionage, including but not limited to governmental, NGO, law enforcement and nonprofit organizations. This latest campaign targeting Ukraine was observed by security analysts at Microsoft. Observed TTPs of ACTINIUM include spearphishing emails using specially crafted Microsoft Word documents that contain malicious macros. Other observed tactics use image files in the emails that are very tiny in scale and report back to the hosting server so that the attacker can check to see if the email was viewed or not. Of course, this depends on whether the recipient chooses to download images or not.Previous analysis on Gamaredon (another name for ACTINIUM) conducted by FortiGuard Labs can be found here. FortiGuard Labs also documented attacks against Ukraine here.What are the Technical Details of the Attack?ACTINIUM uses multiple stage processes that contain payloads that download and execute further additional payloads. Observed staging techniques contain highly obfuscated VBScripts, PowerShells, self-extracting archives, LNK files, etc. To remain persistent, ACTINIUM relies on scheduled tasks. To evade detection and analysis, the usage of randomly generated dictionary words from a predefined word list were used to assign subdomains, scheduled tasks and file names to further confuse analysts. Other observations seen are the usage of DNS records that are frequently changed and contain unique domain names using multiple IP addresses attributed to them.Three malware families were documented in the report, and they are:PowerPunch – Downloader and droppers using PowerShellPterodo – Malware that uses various hashing algorithms and on-demand schemes for decrypting data while freeing allocated heaps space to evade detection and thwart analysis. The malware is evolving, with the usage of various strings to POST content using forged user agents and various commands and scheduled tasks.QuietSieve – These are heavily obfuscated .NET binaries that act primarily as an infostealer.Who/What is Behind this Attack?According to Microsoft, this latest attack is attributed to the Russian FSB. This is per previous reports by the Ukrainian government linking Gamaredon actors to the FSB.Is this a Widespread Attack?No. According to Microsoft, attacks are limited to targeted attacks in the Ukraine.What is the Status of Coverage?Fortinet customers running the latest definitions are protected by the following AV signatures:MSIL/Pterodo.JJ!trMSIL/Pterodo_AGen.B!trMSIL/Pterodo.JK!trMSIL/Pterodo.JF!trMSIL/Pterodo.JI!trPossibleThreatW32/PossibleThreatVBS/SAgent!trW32/APosT.AUC!trW32/Pterodo.AWR!trW32/APosT!trW32/APosT.AWN!trVBA/Amphitryon.1918!trW32/Pterodo.AVL!trW32/Pterodo.AUZ!trW32/Pterodo.ASQ!trW32/GenKryptik.FGHO!trRiskware/PterodoW32/Pterodo.APR!trW32/Pterodo.AQB!trAll network IOC’s are blocked by the WebFiltering client.Any Other Suggested Mitigation?As ACTINIUM uses spearphishing techniques as an entry point, organizations are encouraged to conduct ongoing training sessions to educate and inform personnel about the latest phishing/spearphishing attacks. They also need to encourage employees to never open attachments from someone they don’t know, and to always treat emails from unrecognized/untrusted senders with caution. Since it has been reported that various phishing and spearphishing attacks have been delivered via social engineering distribution mechanisms, it is crucial that end users within an organization be made aware of the various types of attacks being delivered. This can be accomplished through regular training sessions and impromptu tests using predetermined templates by an organizations’ internal security department. Simple user awareness training on how to spot emails with malicious attachments or links could also help prevent initial access into the network.Due to the ease of disruption and potential for damage to daily operations, reputation, and unwanted release of personally identifiable information (PII), etc., it is important to keep all AV and IPS signatures up to date. It is also important to ensure that all known vendor vulnerabilities within an organization are addressed, and updated to protect against attackers establishing a foothold within a network.
Sugar Ransomware in the Wild
FortiGuard Labs is aware that a new ransomware called “Sugar” is in the wild. Reportedly, Sugar ransomware targets consumers rather than enterprises. The first sample of Sugar ransomware appears to have been discovered in the wild in early November. Sugar ransomware encrypts files on the compromised machine and appends “.emcoded01” file extension to them. Victims are asked to pay ransom to recover the encrypted files.What is Sugar Ransomware?Sugar is a ransomware that is written in Delphi and appeared in the wild in November 2021 at the latest. Once run, Sugar ransomware encrypts files on the compromised machine and appends “.encoded01” file extension to them. The malware then displays a ransom note that asks the victim to visit the attacker’s TOR page to pay the ransom in order to recover the encrypted files. The attacker offers to decrypt up to five files to prove that the encrypted files can be recovered upon ransom is paid.The ransom note displayed by Sugar ransomware looks similar to that of REvil ransomware. Also, the TOR site used by Sugar ransomware has close resemblance with that of Cl0p ransomware. However, there is no evidence to suggest that the Sugar ransomware group is associated with REvil and Cl0p threat actors.How Widespread is Sugar Ransomware?Based on the telemetry data collected by FortiGuard Labs, Sugar ransomware infections likely occurred in Canada, Thailand, the United States, Israel and Lithuania.What is the Status of Coverage?FortiGuard Labs provides the following AV coverage against Sugar ransomware:W32/Filecoder.OJD!tr.ransomW32/PossibleThreat

Remote Code Execution in H2 Console JNDI – (CVE-2021-42392)
Update 1/11 – “What is the Status of Coverage” section updatedFortiGuard Labs is aware of newly discovered vulnerability in H2 Database software. The vulnerability is an unauthenticated remote code execution in the H2 database console and similar to Log4j, it is JNDI-based and has an exploit vector similar to it. This vulnerability has been assigned CVE-2021-42392 and was found by security researchers at JFrog. What is H2 Database?H2 is a relational database management system written in Java and is open source. It can be embedded in Java applications or run in client-server mode and data does not need to be stored on disk. What are the Technical Details?In a nutshell, the vector is similar to Log4Shell, where several code paths in the H2 database framework pass unfiltered attacker controlled URLs to the javax.naming.Context.lookup function, which allows for remote codebase loading (remote code execution). The H2 database contains a web based console which listens for connections at http://localhost:8082. The console will contain parameters that are passed by JdbcUtils.getConnection and a malicious URL controlled by the attacker.This vulnerability affects systems with H2 console installed. The vulnerability does not affect machines with H2 database installed in standalone mode. The vulnerability (by default) looks for connections from localhost, or a non remote connection. However, this vulnerability can be modified to listen for remote connections, therefore allowing susceptibility to remote code execution attacks. How Severe is This? Is it Similar to Log4j?According to the report, this is not believed to be as severe as Log4j, because of several factors. The first factor requires H2 console to be present on the system as both the console and database are able to operate independently of each other. Second, the default configuration of accepting connections from localhost must be edited to listen for external connections, which means that default installations are safe to begin with. What is the CVSS score?At this time, details are not available. What Mitigation Steps are Available?FortiGuard Labs recommends that users of H2 database software upgrade to version 2.0.206 immediately. If this is not possible, placing a vulnerable instance behind a firewall or removing access from the public facing internet is suggested. For further details on mitigation, please refer to the JFrog blog “The JNDI Strikes Back – Unauthenticated RCE in H2 Database Console” located in the APPENDIX. What is the Status of Coverage?Customers running the latest IPS definitions (19.237) are protected against exploitation of CVE-2021-42392 with the following signature:H2.Database.Console.JNDI.Remote.Code.Execution
